Phihong develops efficiency level IV 18W universal adapter

Fremont, Calif.Phihong USA has developed an 18W, 3-wire input 48VDC output adapter designated the PSC18U-480(P)-R that meets California's CEC regulation, as well as the federal government's Energy Independence and Security Act that went into effect on July 1.

Aimed at VoIP telephone and videoconferencing applications, the PSC18U-480(P)-R does not inject into the phone line the audible humming noise that is associated with the performances of many other adapters.
